Ecological responses to riverine floods and flow alteration

Creator:: McMullen, Laura E.
Abstract:: Floods are major disturbance events for riverine ecosystems, directly and indirectly impacting organisms and their habitat. In this study I investigated the role of riverine floods and flow alteration in regulating aquatic macroinvertebrate population and community structure. I examined this problem using a variety of methods: a meta-analytic review of...

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...

Aquatic insect adaptations to different flow regimes

Creator:: Yamamuro, Asako Melody
Abstract:: My thesis explored the effects of environmental variability on population dynamics and community composition of aquatic insects. Environmental variability in the form of flow regime in streams can limit the distribution and life-history traits of aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically different flow...

Endocrine regulation of sperm release in an anuran amphibian

Creator:: Whittier, Joan Margaret
Abstract:: The endocrine mechanisms involved in the initiation of sperm release from the vertebrate testis have not been elucidated. A seasonally breeding anuran amphibian, Hyla regilla, was selected as a model for testing the hypothesis that steroid action is involved in gonadotropin-stimulated sperm release. Experiments were carried out in vivo and...

Zoogeography of pelagic shrimps (Natantia: Penaeidea and Caridea) in the North Pacific Ocean

Creator:: Wasmer, Robert Allen
Abstract:: A study was done on the zoogeography of species of oceanic shrimp in the North Pacific from 22°N to 56°N and from 124°W to 145°E, using samples of shrimp collected from 1954 to 1969. These collections were made during the following cruises: John R. Manning Cruise 22, and the Hugh...

The fine structure of the arthrobranch of the crayfish, Pacifastacus leniusculus Dana, with special reference to active ion uptake

Creator:: Morse, Howard Curtis
Abstract:: The gills of an Oregon crayfish, Pacifastacus leniusculus Dana, were examined with histological and histochemical techniques and their fine structure was investigated by electron microscopy. Special attention was given to the structural basis of active ion uptake. The histology of these gills was the same as that of other crayfish...

Population genetics, ecology and evolution of a vertebrate metacommunity

Creator:: Manier, Mollie Kim
Abstract:: Population genetic structure is widespread in many organisms and can be found at small spatial scales. Fine-scale differentiation is the result of ecological and evolutionary processes working together to produce an overall pattern, but the relative importance of these factors in population differentiation is poorly understood. The goals of my...
